Challenge #3

Can you draw a bird in flight?

Did you know: Hollow bones can lighten a bird’s weight to make flying easier, but that’s not the whole story. A University of Massachusetts study found that bird bones can actually weigh just as much as other animals’ bones. The difference is that bird bones have greater bone density than mammal bones, which makes them tougher. They also often have a twisted or curved shape for increased strength when pushed during flight.
